Grind service.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
Below, in conjunction with accompanying drawing, the technical solution of the utility model is further described again:
As it is shown in figure 1, one is sealed in ice core parcel gas extraction device in ice-melt still, specifically include that ice-melt still 1, collection
Heat cover 2, gas furnace 3, sample bottle 4,1# dry pump 5,2# dry pump 6, vacuometer 7, positive-negative pressure gauge 8, thermometer 9, outlet vacuum valve
Va, import vacuum valve vb, 1# vacuum valve v1,2# vacuum valve v2.Ice-melt still 1 is that the body of stainless steel of two semicircle shapes seals composition,
Volume is about at 60 liters.Vacuometer 7 and thermometer 9 it is equipped with, the vacuum detecting respectively and showing in ice-melt still 1 on ice-melt still 1
Number and temperature.There is the collector mat 2 of heat insulation function outside still, be used for reducing in ice-melt still 1 and consume outside heat；Gas furnace 3 is arranged at bottom, uses
Time directly at ice-melt still 1 bottom-heated.Ice-melt still 1 is respectively by pipeline, and a route pipeline is except mouth vacuum valve va and sample bottle 4 even
Logical, on a route pipeline, 1# vacuum valve v1 is connected with 1# dry pump 5 on pipeline, then by 1# dry pump 5 by pipeline and import vacuum valve
Vb connects, then is connected with upper 2# dry pump 6 with pipeline by the 2# vacuum valve v2 on pipeline；Outlet vacuum valve va and import vacuum valve
Vb, respectively at the two ends of sample bottle 4, facilitates connection and the dismounting of pipeline between ice-melt still 1 and 1# dry pump 5；1# dry pump 5 is main
For being responsible in extracting ice-melt still 1 and the gas of connecting line；2# dry pump 6, at 2# vacuum valve v2 end, is mainly used to extract
In sample bottle 4 and the gas of connecting line.Sample bottle 4 is the rustless steel gas cylinder of 1 liter, and it installs positive-negative pressure gauge 8, positive and negative
Pressure gauge 8 is used to refer to the air pressure in sample bottle 4 body.
This device operation principle and operating process are as follows:
I) discharge process of air in system
The ice core sample drilled through is loaded ice-melt still 1, after sealing, opens 1# vacuum valve v1,2# vacuum valve v2 and outlet immediately
Vacuum valve va, closes import vacuum valve vb, and at this moment the air in ice-melt still 1 and sample bottle 4 and connecting line thereof is taken out by 1# dry pump 5
Go out to be discharged in the pipeline between 1# dry pump 5 and outlet vacuum valve vb, by 2# dry pump 6, this partial air is directly arranged the most again
Go out.
II) gentleness purification process again is risen
When the vacuum of vacuometer 7 and positive-negative pressure gauge 8 is reached for 0.1mbar, close 1# vacuum valve v1 and 2# vacuum
Valve va, gas furnace 3 is lighted a fire and is heated up to ice-melt still 1, opens import vacuum valve vb and 2# vacuum valve v2, is at this moment continued by 2# dry pump 6
To sample bottle 4 evacuation, the vacuum of the positive-negative pressure gauge 8 to sample bottle 4 closes outlet vacuum valve when being about 0.02mbar
V2,2# dry pump 6 quits work immediately.
III) ice core parcel gas take gas process
Treat thermometer 9 number of degrees about 4 DEG C on ice-melt still 1, after ice core sample melts completely, open 1# vacuum valve v1, this
Time by 1# dry pump 5 by ice-melt still 1 ice core sample melt after release parcel air pressure enter in 1L sample bottle 4.It is then shut off import
Vacuum valve vb.Protect after finally sample bottle 4 being taken off together with outlet vacuum valve va, outlet vacuum valve vb, positive-negative pressure gauge 8
Deposit, complete the sampling of an ice core sample parcel gas.
Repeat the above steps I) III), start next sample takes gas process.
